Bianchi X-15. I've got one now and had one for my first carry-gun back in '77 or thereabouts. Very comfortable and secure, nice quality leather. Only knock I have on it is that the support back-strap has a tendency to ride up to the bottom of your neck, especially if you're wearing a T-shirt or non-collared shirt. With a collar though, it doesn't bug me at all and it stays concealed better as well. $90 to $110 bucks and available at hundreds of internet dealers.
